Kinase that can phosphorylate the inositol polyphosphate Ins(1,3,4)P3 to form InsP4. Also phosphorylates a racemic mixture of Ins(1,4,6)P3 and Ins(3,4,6)P3 to form InsP4. Does not display inositol 3,4,5,6-tetrakisphosphate 1-kinase activity, but possesses inositol 1,4,5,6-tetrakisphosphate and inositol 1,3,4,5-tetrakisphosphate isomerase activity. Ins(1,3,4,6)P4 is an essential molecule in the hexakisphosphate (InsP6) pathway.
Gene References into Functions
AtITPK4 differs from other family members in that it does not display inositol 3,4,5,6-tetrakisphosphate 1-kinase activity; rather, it displays inositol 1,4,5,6-tetrakisphosphate and inositol 1,3,4,5-tetrakisphosphate isomerase activity. PMID: 17698066
